Question

What weight of drug is in 75 g of a 13% preparation? Round your final answer to 2 decimal places if necessary.

Answer 1

To answer this question we will use the following expression to compute the y% of x:

`x*(y)/(100).`

Therefore the 13% of 75 is:

`75*(13)/(100).`

Simplifying the above result we get:

`3*(13)/(4)=9.75.`

Therefore there are 9.75 g of drug in 75g of a 13% preparation.

Answer: 9.75g.
